going by the max pressure on the tier 41PSI I have never had an overinflated ware pattern at
I have ran as much as 50PSI I did get a slight overinflated ware pattern
going by the inflation pressure on the door tag 28PSI is just plan dangerous with today's tiers the side walls flex so badly the tread lifts off the road
